The closer relatives two species are, the less genomic differences between them. TRUE
Of the following organisms, which has the largest genome size? Commercial rice
Protein-specifying fragments are known as exons
Which of the following is the largest genome sequenced to date? homo sapiens (human)

All of the following are
true about the HOX gene except:
It plays a role in the
brain development of animals.
Noncoding "junk"
DNA is rich in regulatory RNA sequences and may in fact have more of a function
than previously assumed.
